Help Me With My Build

[andrew.odowd]

hello, i am getting problems with my build. my computer was rebooting on desktop with my SLI configuration so i bought an Antec TP-750 and it still reboots either when im at desktop or within a min sometimes it will be stable for the whole day but when i reboot it just gets to the desktop and then reboots however the system is abit more stable using the 4 pin instead of the 8 pin.

i ran each card and both run wonderfully and dont reboot, as soon as i connect both cards and enable SLI is when the rebooting happens.

do the cards have to be in the first 2 PCI express slots since i have 3 or does it matter?

here is my build
AMD phenom x4 955
MSI NF980-G65 MB
2 GTX 465 in SLI
4GB of ddr3 1300mhz Adata Gaming series ram
Antec TP-750 PSU

from my understanding the PSU should be able to run this, right?

Have you tried the cards in the first and second slot/first and third slot (you haven't mentioned how you have them setup right now), to see how it behaves yet?

yes i have, it reboots and then when i make it make on desktop i get a message saying it blue screened.

i have an 8 pin EPS connector and the typical 4 pin and the 4 pin is FAR more stable than the 8 pin. weird since i thought the 8 pin was supposed to be the more stable than the 4 pin.

What happens when you don't enable SLI but keep both cards in the system running separately?
